Description
ALARM COLOR PLATE STRUCTURE OF A MICRO-DIFFERENTIAL PRESSURE GAUGE
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to an alarm color plate structure of a micro-differential pressure gauge, and more particularly, to a pointer gauge structure having at least one alarm plate coupled on a transparent casing.
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to an alarm color plate structure of a micro-differential pressure gauge, and more particularly, to a pointer gauge structure having at least one alarm plate coupled on a transparent casing.
2. Description of the Prior Art A conventional gauge, such as a micro-differential pressure gauge or a pressure gauge, includes a pointer therein. The pointer is rotated according to the pressure. In conjunction with a numeral scale plate in the gauge, the user can read the value. In general, the gauge is set with a security value. For the user to know whether or not the pointer is in the range of safety, the gauge is provided with a safety mark. The conventional mark is secured on an outer edge of the gauge. When the gauge has to be installed in an embedded way, such as in a hole of a flat board of an apparatus, the mark cannot be attached to the gauge because the circumferential edge of the gauge is tightly against the flat board.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.
SUMMARY OF THE INVENTION
One aspect of the present invention provides an alarm color plate structure of a micro-differential pressure gauge. An alarm member is provided on a transparent casing, which doesn't exceed the circumference of the gauge, such that the alarm member can be easily coupled to the gauge which is installed in an embedded way.
In order to achieve this, there is provided an alarm color plate structure of a micro-differential pressure gauge. A transparent casing of a pressure gauge or a micro-differential pressure gauge has a slot which is located corresponding to the range of movement of a pointer or a scale plate. An alarm plate is provided in the slot. The alarm plate has a plurality of areas with different colors or marks for the user to know whether the position and the value of the pointer are normal or not.
la According to an aspect of the invention, there is provided an alarm color plate structure of a micro-differential pressure gauge, comprising:
a gauge base comprising a pointer, an axle and a scale plate therein, the pointer moving through the axle to display a numerical value on the scale plate;

The slot 31 is a curved slot corresponding to the pointer 21 and the scale plate 22.
The slot 31 is formed by a corresponding slide track 32. The slot 31 has a stop portion 33 at one end thereof and an open end 30 opposite the stop portion 33.
The alarm plate 4 is slid in the slot 31. The alarm plate 4 is transparent, translucent or opaque. The alarm plate 4 has one of a safe area 41, an alarm line 42, an abnormal area 43 or a combination thereof.
The alarm line 42 is disposed beside the safe area 41. The abnormal area 43 is disposed beside the alarm line 41 opposing to the safe area 41.
The safe area 41 is green to show a safe state. The abnormal area 43 is red to show an abnormal state.
The present invention may have a plurality of alarm plates 4 in different specifications to change the area and the position of the safe area 41, the alarm line 42 and the abnormal area 43 as desired.
As shown in Fig. 1, one alarm plate 4 is slid in the slot 31 and stopped by the stop portion 33, so that the alarm plate 4 is secured in the slot 31. As shown in Fig. 3, the user can easily know the numerical state of the pointer 21 by the pointer 21 incorporated with the safe area 41, the alarm line 42 and the abnormal area 43.
Fig. 4 is a schematic view to show another alarm plate 5. The safe area 51, the alarm line 52 and the abnormal area 53 of the alarm plate 5 are different from those of the aforesaid embodiment. The numerical area of the alarm plate is changeable.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.
